I believe I dry-fired my 49# @ 62" Bob Lee Hunter recurve a couple days ago, and I don't quite know what caused it.
Hx:
I had taken about 10 or 12 shots with a slightly-thinner-string from the previous owner. (I had never tried this string before now, but the newer string had serving wear and I wanted to be, "safe".) Also I switched to shooting 3-under a few weeks ago. The string had one brass nock under which I place the arrow. After the bang, the arrow tumbled to my feet and the string gave me a nasty red mark in front of my armguard. The brass nock was gone.
Dx:
Is it possible the string nock the wasn't tight enough on the string, ...or that my arrow nocks were too large? ...or that I should use two string nocks for 3-under?
I checked the bow, and the brace height is now ~ 1/4" shorter than when I strung the bow. I don't see any damage that wasn't there previously (there are hairline ?cracks/delaminations? right near the limb bolts that have been there since I bought the bow last fall).
Rx:
I'll disassemble it and check averything, but then if I "see" no damage, is it safe to shoot this bow once I get a nock secured onto the string? (I'd like to eventually double serve the string.)
